OTTO C. IVIANTEUFEL, OF MILWAUKEE, WISCONSIN.

LOOSE-LEAF BINDER.

Application filed November 23, 1912.

To all whom it may concern:

Be it known that I, O'rro C. MANTEUFEL, a citizen of the United States,residing at Milwaukee, county of Milwaukee, and State of Wisconsin, haveinvented new and useful Improvements in Loose-Leaf Binders, of which thefollowing is a specification.

My invention relates to improvements in loose leaf binders.

The object of my invention is to provide a simple and eflicient devicefor perforating, clamping and binding a plurality of loose leavestogether, and my invention is explained by reference to the accompanyingdrawings, in which- Figure 1 is an end view thereof.

Fig. 2 is a front view, with the paper supporting platform in sectionand its operating mechanism removed.

Fig. 3 is a vertical section, drawn on line 00m of Fig. 2.

Fig. 4 is a rear view.

Fig. 5 is a plan view.

Fig. 6 is a perspective view, showing a portion of a bundle of paper,the respective sheets of which are clamped together, preparatory towithdrawing the perforating needles therefrom.

Fig. 7 is a detail view, in section, of a part of the bundle of papershown in Fig. 6; and Fig. 8 is a side view of one of the needlesprovided with a cutting head shown in vertical section, and a detailview of the clamp ing device for holding the needles while the paper isbeing placed thereon.

Like parts are identified by the same reference numerals throughout theseveral views.

1 is a base plate, which is provided at its rear side with a series ofperforating needles 2, upon which separate sheets of paper, bills,

etc. are adapted to be placed from time to time, preparatory to beingthereafter bound together, after a sufficient number of such sheets haveaccumulated. 4 is a pressure bar by which a plurality of sheets areadapted to be pressed down upon the needles 2 at one time, preparatoryto being forced upon the base plate 1. 5 is a guide plate by which theupper ends of the needles are retained in alinelnent with each other asthe sheets of paper are being forced upon them. 6 is an operating leverby which the pressure plate Specification of Letters Patent.

Patented Apr. 3, 1917.

Serial No. 733,031.

Motion is communicated from the lever 6 to the pressure plate throughthe lever supporting shaft 7, arms 8, 8, links 9, 9, link retaining pins10, 10, and 10, 10, which pins 10, 10, are rigidly affixed to the endsof the pressure plate 4, as shown in Fig. 4.

The pressure plate 4 is provided with a plurality of apertures 1.1 forthe reception of the upper ends of the needles 2, as such plate isforced down upon the paper. The guide plate 5 is provided at its frontedge with a plurality of recesses 12 for the reception of the needles.The guide plate 5 is pivotally supported at its center and at each endfrom the rear wall 13 of the machine upon the hinges 14 and said plateis normally retained in the horizontal position shown in Figs. 2 and 3by the recoil of the spiral spring 15, which spring is connected at oneend with said guide plate through the arm 15 and at its other end to thewall 13 through the pin 13. As the sheets of paper are being forced, asindicated by dotted lines 16 in Fig. 3, by the action of the pressureplate 4, said needles are prevented from moving laterally by contactwith the sides of the recesses 12, as they penetrate the paper, when bythe further downward movement of the pressure plate 4, said guide platewill be turned down from the horizontal position to the verticalposition, whereby the sheets of paper are free to pass to the base plate1, as shown in Fig. 3, when the guide plate 5 will be brought back tothe horizontal position shown in Fig. 3 by the recoil of the spiralspring 15. When several sheets 16 have been thus forced upon the needlespast the guide plate, the operating lever 6 is drawn backwardly by therecoil of the spiral spring 19, one end of said spring 19 beingconnected with the lever supporting rock shaft 7, while its opposite endis secured to the shaft supporting bracket 7 18 represents a bundle ofsheets of paper supported upon the base plate 1, preparatory to beingbound together. When the required number of sheets have been added tothe bundle 18, a temporary binding bar 33 shown in dotted lines in Fig.2, is placed transversely across the rear end of the bundle directlybeneath the lower ends of the binding screws 34, when said binding bar37 is a hand wheel by which the binding screws 34 areoperated.

' hen the sheets of the bundle have been thus compressed together byturning down the binding screws 34 upon the temporary binding bar 33,the series of needles 2 are withdrawn from said sheets as hereinafter,

described. The several needles 2 of the series are each provided attheir upper ends With a hook 38, as shown in Fig. 6, for the receptionof a binding cord, indicated by dotted lines 38, whereby the bindingcord which is placed in such hooks as indicated in Fig. 6, is adapted tobe drawn down through the perforations in the paper by the act ofwithdrawing the needles from such perforations, whereby the binding cordis left within the perforations, as indicated by dotted lines in Fig. 7.The several needles 2 of the series are rigidly secured at their lowerends to the rear edge of thebase plate 1 by and between the opposingsurfaces of the transversely arranged bar 39 and'the opposing bar 40formed on the rear lower edge of the rear wall 13 such bars beingsecured together by the clamping bolts. 41, 41 and wing nuts 42, 42. Themembers 13, 39, 40,

40, 41, 41, 42 and 42, as shown in Fig. 8 are connected at one end toone of the vertical standards 35 by the hlnge bolts 43, 43, and

v at their opposite ends with the other vertical standard 35 by thevertical pins43.

' When the desired number of sheets have in the recesses 46 of thevertical side brackets 47,47, are withdrawn, whereby said brackets 47,together with the rear wall 13 and all the operating mechanism connectedtherewith, including the operating lever 6,

rock shaft 7, members 8, 9, 10, 10', 4, 5, 13,

14, 15 and l5, are allowed to drop away from and out of'engagingconnection w1th the lower end of the needles, whereby said needles arepermitted to remain in the bun dle of papers. By the downward movementof theurearwall 13, the vertical pins 43" are brought outof engagementwith the vertical standard 35 on the left, as shown in Fig. 4', wherebysaid rear wall 13, together with all of said parts connected therewith,are adapted tobe swung rearwardly a quarter of a revolution upon thesupporting hinge pins 43, wherebythe operator has free access to therear edge of the bundle of paper, which is left upon the platform 1, asshown in Fig. 6, when the cutting heads 61 are removed from the upperends of the needles and the binding cord 38 is passed beneath the hooks38 of said needles, when the needles are manually withdrawn from thebundle of paper 18, whereby the binding cord is drawn through theperforations 18 in said bundle as indicated in Fig. 7, when the ends ofsaid binding cord are secured together, whereby the sheets of paper arepermanently bound.

' The hinge pins 43, 43 are connected with one end of the rear wall 13by the supporting brackets 40 and 50 and bolts 52 and 53, while theopposite end of said rear wall 13 is temporarilyconnected with thevertical standard 35 by the brackets 40 and 54, pins 43, 43 and bolts 56and 57. (See Fig. It will be understood that when forcing the needles 2through the sheets of paper as they are successively placed thereon,said needles are respectively provided with said cutting heads 61, asshown in Figs. 6 and 8, and that said heads 61 are removably attached.to the upper ends of the needles as shown in said Figs. 6 and 8. When,however, the required number of sheets have been placed upon the needlesto make a bundle, said cutting heads 61 are manually removed from thetops of the needles, as stated, whereby the hooks 38 are exposed for thereception of the binding cord 38", when the binding cord is drawnthrough the perforations, as previously described by manuallywithdrawing the needles therefrom. The cutting heads 61 comprise acylindrical member 59, which is adapted to closely fit upon the upperends of the needles, whereby they are retained in place. Said cuttingheads are also provided at their upper ends with cutting edges 60, 60,which are adapted to penetrate the sheets of paper as they are placedthereon, while the side of each cutting head is provided with anaperture 58, through which the waste paper, which is severed from thesheets of paper as such sheets are placed over the cutting heads, isadapted to escape from the cutting heads.

As a means of forcing the refuse paper from the upper ends of thecutting heads 61, I have provided a series of wire hooks 62, the lowerends 63 of which terminate directly above the opening 64 in said headsand are adapted to enter the same as said hooks ar drawn down in the actof forcing the paper upon said cutting heads and needles, whereby therefuse paper is forced out through the aperture 58 of said cuttingheads. The wire hooks 62 are supported at their lower ends from the rearwall 65 of the pressure plate 4. 66 is a temporary paper supportingplatform, which is adapted to support the paper beneath the pressureplate as the several needles 2 are forced through the same. hen,however, the sheets of paper have been perforated by the series ofneedles 9, said temporary paper supporting platform 66 is forced frombeneath the sheets of paper in a direction indicated by the arrow 71 inFig. 8, whereby the sheets of paper are free to pass down upon thebundle 18, as shown in said Fig. 3.

Motion is communicated from the operating lever 6 to the papersupporting platform through shaft 7, arms 8, 8, bolts or rivets 10, 16,links 9, 9, bolts or rivets 10, 10, pressure bar f, pivotal bolts 67, 67and links 68, 68, which links 68, 68 are provided at their lower endswith longitudinal slots 69, 69 for the reception of the pins or rivets70. The pins or rivets 7 0 also serve to connect the links 68 with thelinks 66", as shown in Fig. 5. Thus, it will be obvious that as theoperating lever 6 is moved forwardly, the sheets of paper are firstforced upon the upper ends of the series of needles 2, when by thefurther forward movement of said operating lever, said paper supportingplatform is withdrawn from beneath the sheets of paper and thrownforward, as indicated by said arrow 71 in Figs. 1 and 3, whereby thepaper is free to pass down to the lower end of the needles and rest uponthe bundle 18.

It will be understood that preparatory to swinging the rear platform andother 00- operating parts upon its supporting hinges, as previouslydescribed, it becomes necessary to disengage the upper ends of the link68 from the pressure plate 4:, and to accomplish this object the upperends of said links are provided with recesses 72 communicating fromtheir lower edges to the openings for the bolts 67, whereby said linksare free to be thrown back and disengaged from said pins, whereby thepaper supporting platform is entirely disengaged from the rear wall 13and said rear wall 13 and other cooperating parts are free to be turnedback upon their supporting hinges, as previously described.

The paper supporting platform 66 is sup ported from the base plate 1 atits respective edges by the members 66 and pivotal bolts 67 said bolts67" passing through the upper ends of said members 66", and into theside walls of said paper supporting platform near its center.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
